---------------------+------------------------
 FreePascal includes a nice little binary that has standalone interest, and
 which can be distributed on its own, technically speaking: `chmcmd`.

 This can take the place of MS HTML WorkShop help compiler (hhc.exe) in
 doxygen applications (`HHC_LOCATION`); a quick comparison between the chm
 files built through doxygen by hhc.exe and chmcmd revealed no obvious
 information or function loss.

 The only alternative I am currently aware of to create a single archive
 file containing what would otherwise be a possibly very large set of HTML
 files is Qt's compiled help (.qch); in my testing these can be twice as
 big as .chm files and recent regressions in Qt's Assistant make them a
 less appealing alternative.

 I'm working on an updated `port:kchmviewer`; having the chmcmd command
 available without having to install the whole FreePascal environment would
 definitely be a win, esp. for the API documentation generated by my KF5
 ports.

 I don't think the command itself is required by FreePascal (to be
 confirmed, but it's discussed on their wiki as more of a demonstration
 than an actual tool). I haven't looked at specifics, but a priori it
 should be possible to build just this executable in the FreePascal source
 tree. This would lead to a (sub)port that has a build dependency on
 port:fpc but ships a standalone executable (to be installed in
 ${prefix}/bin, of course).

 I *presume* that the (L)GPL-2 makes it impossible for me to bundle the
 executable with my `port:kf5-kapidocs` ?
